Application niea February 27, 1912. Serial 1%.680314.

To all whom it may comm:

Be it known that I, LACEY Y. WnJJAMs, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Dust-Guards, of which the following is a specification.

My invention relates to dust guards, and especially such as are adapted for use in connection with car ournal boxes, the object being the provision of a guard of very simple construction and relatively cheap in first cost and at the same time durable and eflicient in preventing the admission of'dust and dirt to the interior of the box.

My invention consists incertain novelties of construction and combinations of parts as hereinafter set forth and claimed.

The accompanying drawing illustrates an example of the physical embodiment of the invention constructed according to the best mode of procedure. I have so far devised Figure 1 is a vertical section of a journal box and dust guard in elevation and a side view of a journal within the box. Fig. 2 is a plan view of my improved dust guard, one-half'of'the flexible or yielding material being removed to show the spring. Fig. 3 is an enlarged section on line :v-wp, Fig. 2, and showing by dotted lines the positions of the spring and yielding material or packing when the guard is within the chamber at the back of the journal box.

Referring to the figures, the numeral 1' designates a journal box of any well known construction with a chamber 2 at the back provided with an opening 3 at the top for the insertion of a guard; 4, a car axle journal; 5, the cylindrical portion of the journal adjacent the bearing; 6, the dust guard body of wood or other suitable material; 7, a circular or curved opening in the body; 9, a metallic coiled or helical spring secured to one face of the body of the guard adjacent the opening therethrough by staples 10, as shown, driven into the body and lapping over the wire of the spring; and 11 is flexible material, such as leather, woolen or cotton or other fabric, constituting the packing. having one edge v12 secured to the body of the guard outside the spring by tacks or nails 13, passed over the spring and through 'when worn out or torn.

the opening 7 and the edge 14 secured by tacks or nails 15 to the opposite face of the body of the guard.

-As will be seen on reference to Fig. 3, suflicient slack or excess of material is provided between the nailed edges of the flexible material or packing to create or cause folds therein. When inserted within the chamber at the back of the box the spring being held by the body of the guard will be flattened or compressed so that the flexible material in contact with the spring will frictionally engage the vertical surface of the box bounding the chamber upon one side and the body of the guard will frictionally engage the surface of the opposite vertical wall, thus preventing any dust or dirt passing to the interior of the box from the chamber. By reason of the flattening of the spring when in the chamber, the quantity of slack in the flexible material or packing will be increased and the material be. forced outwardly and radially from the edge of the opening and against the journal, as clearly illustrated, thus closing the opening between the surface defining the opening in the body of the guard and the exterior surface of the journal.

Obviously, I have produced a very simple,

cheap and durable guard and one which can be readily repaired when necessary by replacing the flexible material or packing What I claim is:

1. A dust. guard comprising a body portion with an opening therethrough for the passage of the journal, flexible material or packing surrounding the opening and the opposite edges of said flexible material or packing secured to opposite surfaces of the body portion, and yielding spring means disposed beneath the flexible material or packmg and engaging the surface'of the body of the guard, for the purpose set forth.

2. A dust guard comprising a body portion with an opening therethrough for the passage of the journal, flexible material or packing surrounding the opening and the opposite edges of said flexible material or packing secured to opposite surfaces of the body portion, said flexible material having slack or folds therein between its edges when in secured position, and yielding spring means disposed beneath the flexible body portion, and a. coiled spring disposed 10 material or packin and engaging the surbeneath the flexible material or packing.
